Answer:

x = 4\frac{2}{3}      y = 7        and    z =3\frac{1}{3}

This implies the equation has just one solution

Step-by-step explanation:

To create the equation, we need to be able to write the information  or interpret the question mathematically.

Let x equal to the number of red balls.

Let y equal to the number of blue balls.

Let z equal to the number of green balls.

From the question; "The number of red balls is 2/3 the number of blue balls" can be mathematically written as :  x = \frac{2}{3} y  ---------------------------(1)

The next statement; "The number of green balls is 1 more than 1/3 the number of blue balls" can be written mathematically as: z = 1+\frac{1}{3} y ----------------------------(2)

The next statement; "she has 15 balls."  can be mathematically written as:     x + y + z = 15 ----------------------------------------(3)

Substitute  equation (1) and equation (2) into equation (3)

\frac{2}{3} y + y +1 +\frac{1}{3} y  =  15

We can rearrange this equation

\frac{2}{3} y  +\frac{1}{3} y + y +1 =  15

\frac{3}{3} y  + y + 1 = 15

y + y + 1 = 15

2y + 1 = 15

subtract 1 from both-side of the equation

2y + 1 -1 = 15 -1

2y = 14

Divide both-side of the equation by 2

2y/2 = 14/2

y = 7

Substitute y = 7 into equation (1)

x = \frac{2}{3} y

x = \frac{2}{3} (7)

x = 14/3

x = 4\frac{2}{3}

Substitute y= 7 in equation (2)

z = 1+\frac{1}{3} y

z = 1+\frac{1}{3} (7)

z = 1+ 7/3

z = 10/3

z =3\frac{1}{3}

Therefore;

x = 4\frac{2}{3}      y = 7        and    z =3\frac{1}{3}

This implies the equation has just one solution.

It would have one solution since you know the total number of balls

What is the first ordered pair and the second ordered pair?
Delvig [45]
When x=-5, y=(1/5)*(-5)-1=-2, so the first order pair is (-5,-2)
when y=-1, -1=(1/5)x-1, (1/5)x=0, x=0, so the second ordered pair is (0, -1)

Answer:

Below.

Step-by-step explanation:

30 kg 500g + 28kg 700g

= 58kg + 1200g

= 59kg 200g.

Difference

= 30 kg 500g - 28kg 700g

= 2kg + 500 - 700

= 2kg - 200g

= 1kg 800g.
